Alien Space Shooter

This is my 2D shooter project. I made the following significant modifications.

1. I've added different backgrounds to each level the player succeeds.

2. I've added sound affects when a player reaches a new level as well as when the game is over.

3. I've added more enemies to defeat within each level as the player reaches a higher level.
